Larval stages of the Botan shrimp Pandalus nipponensis Yokoya, 1933 (Decapoda: Caridea: Pandalidae) under laboratory conditions, with notes on its lecithotrophic development

Larval development ofPandalus gracilisStimpson (Crustacea: Decapoda: Pandalidae) reared in the laboratory

“…These two shallow water species have large eggs and relatively advanced first larvae with abbreviated development (Kurata 1955;Mikulich and Ivanov 1983). Taishaku et al (2001) mentioned that P. nipponensis also shows ''bottom-dwelling behaviour'' after hatching with welldeveloped pereiopods. In P. gracilis, only 64 larvae were hatched from one ovigerous female.…”

“…The complete larval development of Pandalus has been described for the following 11 species: P. jordani by Rothlisberg (1980), P. eous by Kurata (1964), P. borealis by Haynes (1979), P. goniurus by Haynes (1978), P. stenolepis by Needler (1938), P. hypsinotus by Haynes (1976), P. danae by Berkeley (1930), P. prensor by Mikulich and Ivanov (1983), P. nipponensis by Taishaku et al (2001), P. platyceros by Price and Chew (1972), and P. latirostris by Kurata (1955); P. montagui was described incompletely. However, no descriptions of the larval stages of P. gracilis have been published so far.…”
